This study evaluated the structure of swards planted with Urochloa brizantha cv. BRS Paiaguas and BRS Piata under the eucalyptus shading system, fertilized via foliar at the beginning of the dry and rainy seasons. The experiment followed a randomized block design with a 4×2×2 (4 leaf fertilizer levels × 2 systems × 2 seasons) factorial arrangement. The results were analyzed using the GLIMMIX PROC of SAS University while means were compared by the T-test at 5%. Foliar fertilizer had a significant (P≤0.05) effect on cv. BRS Paiaguas stem mass under shading while the 3 and 6 L/ha levels produced the lowest (P≤0.05) masses. The forage and root masses were not significantly affected (P≥0.05) by the systems and seasons whereas the dead material mass was not influenced by the seasons. The shading system resulted in (P≤0.05) significantly lower dead material mass for both cultivars and higher (P≤0.05) leaf and stem masses for the cv. BRS Piata. In the rainy season, leaf and stem masses were greater (P≤0.05). Foliar fertilization up to 6 L/ha favored the stem control in cv. BRS Paiaguas under shading. The resulting masses of forage, dead material, and root allow concluding that the cultivars adapted well to the shading and dry season.

This study aimed to evaluate the effects of a biostimulant on the morphogenesis, structure, productivity, and chemical composition of Urochloa brizantha cv. Marandu, managed under two nitrogen fertilization levels. Collections were carried out during the dry (June to September) and the rainy season (September to April). The experimental area was divided into 48 plots of 8 m2 each, using a randomized block design in a 4 × 2 factorial arrangement (0, 1, 2, and 3 L ha−1 of biostimulant × 50 and 150 kg N ha−1 year−1), and subdivided over time into dry and rainy seasons. Treatments were applied in a single dose. An interaction was observed between biostimulant and nitrogen fertilization for the total forage dry matter production and daily forage dry matter production, in which an increase of 30.1 and 25.3% was observed in the total dry matter production and 33.7 and 27.6% in the daily dry matter production when using 1 and 2 L ha−1 of biostimulant, respectively, compared to the non-application of biostimulant and with fertilization of 50 kg N ha−1 year−1. The leaf life-span showed a triple interaction (biostimulant × nitrogen fertilization × season), and a decomposition of the interaction showed that the fertilization of 150 kg N ha−1 year−1 provided a shorter leaf life-span during the dry season, with no difference for the other combinations of factors. No interactions were found for the chemical-bromatological composition, with no differences for the biostimulant application. Biostimulant doses of 1 and 2 L ha−1 increase the dry matter production per hectare in the nitrogen fertilization of 50 kg N ha−1 year−1, but its action is not effective with the highest nitrogen fertilization (150 kg N ha−1 year−1).

Objective: Evaluate the forage yield of Urochloa brizantha cv. Insurgente at differentcutting heights.Design/ methodology/ approach: the experiment was carried out at the Universidaddel Papaloapan, Loma Bonita, Oaxaca, Mexico. Four cutting heights were evaluated (5,10, 15, and 20 cm) during the rainy, norther, and dry seasons. The experiment followeda randomized block design with four replicates. We evaluated plant height (PH), greenmatter yield (GMY), dry matter yield (DMY), growth rate (GR), and morphologicalcomponents, such as leaf yield (LY), sheath yield (SY), and stem yield (StY).Results: the cutting height and season interaction was significant for all the evaluatedvariables (P?0.01). The highest PH (42 cm) was obtained with a cutting height of 20 cmduring the rainy season. The highest GMY and DMY (2,484 and 606 kg ha -1 ,respectively) were obtained with cutting heights of 15 cm during the rainy season. Thesevalues were similar (P>0.05) to those obtained at 20 cm (2,410 and 582 kg ha -1 ,respectively). The highest LY, SY, and StY values were obtained with cutting heights of15 and 20 cm during the rainy season. The highest GR (31 kg MS ha -1 day -1 ) wasobserved during the rainy season, regardless of cutting height.Findings/ conclusions: for each of the evaluated seasons, cutting heights of 15 and 20cm resulted in the highest forage yields of U. brizantha cv. Insurgente.

[APPLICATION OF LEAF FERTILIZER TO INCREASE THE GROWTH AND YIELD OF BAWANG DAYAK (Eleutherine palmifolia (L.) Merr)]. Bawang Dayak (Eleutherine palmifolia (L.) Merr) is a potential medicinal plant and required improved growth and yield through the application of appropriate fertilizers. This study aimed to increase the growth and yield of bawang Dayak by determining the optimum concentration and time interval of foliar fertilizer application. The experiment was arranged in a completely randomized block design factorial. The first factor was the concentration of foliar fertilizer, consisting of 0,1, 2, and 3 g/L. The second factor was interval application of foliar fertilizer, consisting of every day, every 3 days, every 6 days, and every 9 days. The results showed that bawang Dayak did not show a significant response to foliar fertilizers. However, there was an interaction between the concentration and interval of foliar fertilizer application which had a significantly different effect on plant height. The highest plant height occurred at intervals of 3-day foliar fertilizer application with a concentration of 3 g/L. The concentration of foliar fertilizer had a significant effect on the variables of plant height, bulb fresh weight, as well as the bulb numbers. All concentrations of foliar fertilizer (0-3 g/L), and time intervals of foliar fertilizer application (1-9 days) affected the same growth and yield response of Bawang Dayak.

AbstractTitanium is one of a plant biostimulators. It stimulates life processes, growth and development, as well as affects physiological and biochemical pathways, often increasing biomass production and enhancing yield. An open field experiment was conducted in the years 2011-2013 in Polanowice, Poland to investigate the effects of titanium foliar fertilization on the growth of timothy grass (Phleum pratenseL.). This single-factor, randomized block design study was performed in four replicates on research plots with the area of 10 m2each. The substrate was black loess soil (chernozem) typical for top class farmland. Titanium fertilizationvialeaf spray was performed with a water solution of Tytanit® at three doses of 0.2, 0.4, and 0.8 dm3· ha−1. Foliar fertilization with the highest dose of Tytanit® significantly increased seed yield, thousand grain weight and germination capacity. Moreover, the middle dose of Tytanit® (0.4 dm3· ha−1) was enough to observe a positive effect on the sample.

Antioxidant is a term related to the activity ability and properties of the active ingredient.  The higher the ability of the antioxidant activity of an active ingredient, the stronger its antioxidant properties are to ward off various free radical compounds due to oxidative stress. The activity ability and antioxidant properties of tea shoots often fluctuate with changing seasons.  This study investigated the effect giving nitrogen levels in organic + inorganic liquid fertilizers on the ability of activity and antioxidant properties of tea shoots in different seasons. The experimental design used was a over season complete randomized block design consisting of 5 levels of fertilization concentration in the rainy and dry seasons. The results showed that the application of organic + inorganic liquid fertilizers without the addition of N concentration in the dry season had a significant effect on the antioxidant activity of tea shoots by 88.14%, and 34.15% higher than control plants in the rainy season and 41.81% more. Height of control plants in the dry season. The IC50 value of tea shoots in the rainy season and dry season has very strong antioxidant properties where the order of the antioxidant properties of the control plants < all concentrations of adding N to organic + inorganic liquid fertilizers < concentration of organic + inorganic liquid fertilizers without the addition of N.Keywords: Ability Antioxidant Activity, Organic + Inorganic Liquid Fertilizer, Tea shoots, Antioxidant Properties.

Effect of prunning technique and foliar fertilizer application had been conducted to improve yield of pecco in the Research Institute for Tea and Cinchona experiment station, Gambung, Indonesia with altitude of 1.350 m above sea level, and with andysol soil type. The experiment was held from July to October 2015 in tea production field area containing 480 plants. The clone was GMB 7and was in the fourth prunning year, interval of plucking pecco was seven days. The experiment was arranged in a randomized block design with four treatments, replicated six times. Foliar fertilizer application was performed following every plucking. The results indicated that breaking apical dominance of tea short by 5 cm–10 cm of prunning above plucking table combined with foliar fertilizer application of N 1% and ZnSo<sub>4</sub> 2% + 0,1% of humic acid, could increase weight of pecco per plot in the first nine weeks of the prunning. This treatment was better than the other three. But the percentage of pecco shoots was low, lower than 50%, the weight of one pecco was also very low 0,7 g, indicating that the treatment of harvesting pecco in the fourth prunning year was not recomended to be practiced in improving yield of pecco.

In order to optimize machinery use, the application of herbicides has been performed at different times of the day and night. Therefore, knowledge about the pesticide that will be used and how the spray volume and time of application affect the effectiveness of the product is very important. Thus, the objective of this work was to study the influence of spray volume and different time of application on the control of Urochloa brizantha by different doses of glyphosate. The treatments were arranged in a 5 x 3 x 2 factorial scheme in a randomized block design with four replications. Five doses of glyphosate (0; 1080; 1440; 1800 and 2160 g∙ha-1∙a.e.), three times of application (morning, afternoon and evening) and two spray volumes (50 and 100 L·ha-1) were evaluated. A control assessment was performed at 21 days after application, in addition to the accumulation of dry matter and the leaf area index on the regrowth. A satisfactory control of the grass was obtained for applications performed in the morning and afternoon, without interference of the volume applied and the doses tested. Evening application reduces the effectiveness of glyphosate in Urochloa brizantha burndown.

The study aimed to evaluate the agronomic characteristics of elephant grass (Pennisetum purpureum Schum.) genotypes on energy production in the combustion form. A randomized block design with 3 repetitions was used. The treatments were arranged in subdivided plots scheme, considering as a plot the genotypes and as subplots, the harvest season. The agronomic characteristics plant height (H), leaf length (LL), leaf blade width (LBW), stem diameter (SD), tillers number (TN), stem percentage (SP), dry matter yield (DMY) were evaluated. The rainy season provided greater H to elephant grass genotypes with height above 3.5 m. The average SP obtained by the genotypes was 68.21% and 67.21% to the first and second year of cultivation, respectively, which gives the biomass good quality of burning. The rainy season provided greater DMY comparing to the dry season. In the first year of cultivation there were genotypes with annual dry matter yield (ADMY) above 50 ton ha-1 year-1, however, the non-maintenance of soil fertility promoted the reduction of 39.17% and 39.05% in the DMY and ADMY, respectively. Analyzing the agronomic characteristics, we conclude that the promising genotypes of elephant grass to produce energy in the form of direct combustion are CNPGL 91-25-1, Cubano Pinda, BRS Canará, Porto Rico and Mercker.
